One of the main differences between box dye and salon dye is that box dye is much more limited in terms of the colors it can create. Box dye is also more likely to cause damage to your hair since it doesn't contain the same level of quality ingredients as salon dye does.

The main purpose of the Colour Box is to develop a child's visual sense of colour. Primary colours (Red, Yellow and Blue) are introduced in Colour Box 1, which is first presented to a child at 2.5 to 3 years of age. Colour Boxes 2 and 3 add more tablets to the mix, expanding a child's colour knowledge.

Salon hair color typically offers a higher-quality and longer-lasting color that blends well with your natural hair color, while box dye may result in a less vibrant and shorter-lasting color that can be more prone to fading and damage.

Salons use semi-permanent color to add depth to your color, grow out permanent color, or add gloss and shine to your strands. “It can even create a highlighted look, depending on the hair and the shade selected,” Shade says. Which is better for your hair, permanent or semi-permanent?
